我正在制作图像'上行系统。 但是我收到了一个错误, / accounts / upload_save /的ValueError 对于带有基数为10的int(),文字无效:'' 。 我认为这个错误是int类型值不在参数中。

我的追溯显示

 photo_obj = Post.objects.get(id=photo_id) 

错了。 但是get()可以在int类型值中,所以我无法修复我的错误。 我该如何解决?

我在views.py,

中写道
@require_POST
def regist_save(request):
    form = RegisterForm(request.POST)
    if form.is_valid():
        user = form.save()
        login(request, user)
        context = {
            'user': request.user,
        }
        return redirect('profile')


    context = {
        'form': form,
    }
    return render(request, 'registration/accounts/regist.html', context)


def photo(request):
    d = {
        'photos': Post.objects.all(),
    }
    return render(request, 'registration/accounts/profile.html', d)


def upload(request, p_id):
    d = {
        'p_id': p_id,
    }
    return render(request, 'registration/accounts/profile.html', d)


def upload_save(request):
    photo_id = request.POST.get("p_id", "")
    photo_obj = Post.objects.get(id=photo_id)
    files = request.FILES.getlist("files[]")

    photo_obj.image1 = files[0]
    photo_obj.image2 = files[1]
    photo_obj.image3 = files[2]

    photo_obj.save()

    return redirect("registration/accounts/profile.html")
在urls.py中

from django.conf.urls import url
from . import views
from django.contrib.auth.views import login, logout

urlpatterns = [
    url(r'^regist/$', views.regist,name='regist' ),
    url(r'^regist_save/$', views.regist_save, name='regist_save'),
    url(r'^profile/$', views.profile, name='profile'),
    url(r'^upload/(?P<p_id>\d+)/$', views.upload, name='upload'),
    url(r'^upload_save/$', views.upload_save, name='upload_save'),
]
profile.html中的

{% extends "registration/accounts/base.html" %}
  {% block content %}

  <!DOCTYPE html>

  <html lang="ja">
    <head>
      <meta charset="utf-8">

    user.date_joined: {{ user.date_joined }}

    <div class="container">
      <form action="{% url 'accounts:upload_save' %}" method="POST" enctype="multipart/form-data">
        {% csrf_token %}
        <input type="file" name="files[]" multiple>
        <input type="hidden" value="{{ p_id }}" name="p_id">
        <input type="submit" value="Upload">

    </div>

    </body>
  </html>

  {% endblock %}

photo_id = request.POST.get("p_id", "")

此POST请求中没有p_id,因此photo_id设置为空字符串''

photo_obj = Post.objects.get(id=photo_id)

然后您尝试使用此空字符串获取photo_obj,因此它会告诉您ValueError: invalid literal for int() with base 10: ''
